Description

Technical Field

[0001] The utility model relates to the field of food preservation, in particular to a low-temperature fresh-keeping device for wolfberry fruit. Background Art

[0002] Fresh wolfberries are not easy to store and transport. In order to facilitate the storage, transportation and sales of wolfberries, wolfberries are generally dehydrated to make dried wolfberries. Fresh wolfberries will lose a lot of nutrients in the process of making dried wolfberries. At the same time, in order to ensure the quality of dried wolfberries, some harmful substances are sometimes introduced into the wolfberries, thus affecting the practical value of the wolfberries themselves. With the cultivation of wolfberry varieties by scientific researchers, many fresh wolfberry varieties with good taste have been launched. Many consumers are also willing to try and accept eating these fresh wolfberry varieties.

[0003] A Chinese patent document with publication number CN112938102A discloses a fresh wolfberry preservation device, which maintains a stable temperature around the wolfberry fresh device by providing an outer protection box, and a layer of ice particles between the wolfberry fresh device box and the outer protection box. The wolfberry fresh device box is provided with air holes to facilitate the breathing of the wolfberry fresh device. Correspondingly, a breathable membrane is provided at the upper end of the outer protection box to facilitate gas exchange with the outside world. A water collecting mechanism for containing water is provided at the bottom of the outer protection box. The water collecting mechanism is located directly below the wolfberry fresh device box to collect ice water melted from the ice particles.

[0004] However, after the water collection mechanism in the original device collects the ice water, it allows the ice water to evaporate slowly, so that the temperature inside the storage box may rise, which in turn leads to a decrease in the low-temperature preservation effect. In addition, the ice water also loses water during its own evaporation process, so it is necessary to improve the structure of recycling ice water in the original equipment. Utility Model Content
